How to Convert rJ to Erg?
Converting from rJ to Erg is a straightforward process. Follow these steps to ensure accurate conversions from rontojoule to erg:
- Select the Rontojoule Value: Start by determining the rontojoule (rJ) value you want to convert into erg (Erg). This is your starting point.
- Multiply by the Conversion Factor: To calculate rontojoule to equivalent erg amount, multiply the selected rJ value by 1e-20.
- Illustration of Multiplication:
- 1 rJ = 1e-20 Erg
- 10 rJ = 1e-19 Erg
- 100 rJ = 1e-18 Erg
- Find the Conversion Result: The result of this multiplication is your converted value in erg unit. This represents the same energy but in a different unit.
- Save Your Erg Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in ergs.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the rontojoule value by 1e+20. This alternative method also gives you the correct energy in ergs.
- Illustration of Division:
- Erg = rj ÷ 1e+20
What is Energy?
Energy is the capacity of a physical system to do work or produce heat. The SI unit is the joule (J), defined as the work done when a force of one newton is applied over one meter (1 J = 1 N·m = 1 kg·m²/s²). Other important units include the kilowatt-hour (kWh)—used on electricity bills (1 kWh = 3.6 MJ)—the calorie (cal)—used in nutrition (1 food Calorie = 1 kcal = 4,184 J)—and the electronvolt (eV), used in atomic and particle physics (1 eV = 1.602 × 10⁻¹⁹ J).
What is Rontojoule?
Rontojoule (symbol: rJ) is a metric unit of energy equal to one quectillionth (10-27) of a joule. It was introduced in 2022 as part of the expanded SI prefix system and is intended for expressing extremely small quantities of energy in advanced scientific research. Learn more about rontojoule.
What is Erg?
Erg (symbol: erg) is a unit of energy in the centimeter-gram-second (CGS) system, equal to 1 × 10-7 joule. Although largely replaced by SI units, the erg still appears in astrophysics, older scientific literature, and some fields of physics. Learn more about erg.

Rontojoule to Erg Examples
Example 1:
Convert 0.8 Rontojoule energy to Erg unit.
Solution:
We know that one Rontojoule is equivalent to 1e-20 Erg.
Therefore,
0.8 rJ = 0.8 x 1e-20 Erg.
0.8 rJ = 8e-21 Erg.
Hence, 0.8 Rontojoule is approximately equal to 8e-21 Erg.
Example 2:
Convert 8 Rontojoule energy to Erg unit.
Solution:
We know that one Rontojoule is equivalent to 1e-20 Erg.
Therefore,
8 rJ = 8 x 1e-20 Erg.
8 rJ = 8e-20 Erg.
Hence, 8 Rontojoule is approximately equal to 8e-20 Erg.
